I have attached an eprom compatibility chart picture to
help you understanding wich type of eproms use your drum
machine and wich sounds are interchangeable.
You can also listen some sound samples if you want.

Single EPROM sounds can be used in a DMX or DX multi-EPROM
cymbal voice by filling the unused EPROM sockets with “silent” EPROMs,
filled entirely with zeroes. If you leave the unused sockets empty,
there will be a lound thump at the end of the sound.
